CVE-2016-3189 2 Bzip, Python 2 Bzip2, Python 2025-04-12 4.3 MEDIUM 6.5 MEDIUM
Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start of the block.
CVE-2014-9365 2 Apple, Python 2 Mac Os X, Python 2025-04-12 5.8 MEDIUM N/A
The HTTP clients in the (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib libraries in CPython (aka Python) 2.x before 2.7.9 and 3.x before 3.4.3, when accessing an HTTPS URL, do not (a) check the certificate against a trust store or verify that the server hostname matches a domain name in the subject's (b) Common Name or (c) subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2014-1912 2 Apple, Python 2 Mac Os X, Python 2025-04-12 7.5 HIGH N/A
Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string.
CVE-2013-7440 1 Python 1 Python 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2016-4472 4 Canonical, Libexpat Project, Mcafee and 1 more 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more 2025-04-12 6.8 MEDIUM 8.1 HIGH
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
CVE-2016-5699 1 Python 1 Python 2025-04-12 4.3 MEDIUM 6.1 MEDIUM
CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython (aka Python) before 2.7.10 and 3.x before 3.4.4 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL.
CVE-2015-1283 8 Canonical, Debian, Google and 5 more 13 Ubuntu Linux, Debian Linux, Chrome and 10 more 2025-04-12 6.8 MEDIUM N/A
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.
CVE-2010-2089 1 Python 1 Python 2025-04-11 5.0 MEDIUM N/A
The audioop module in Python 2.7 and 3.2 does not verify the relationships between size arguments and byte string lengths, which allows context-dependent attackers to cause a denial of service (memory corruption and application crash) via crafted arguments, as demonstrated by a call to audioop.reverse with a one-byte string, a different vulnerability than CVE-2010-1634.
CVE-2011-4944 1 Python 1 Python 2025-04-11 1.9 LOW N/A
Python 2.6 through 3.2 creates ~/.pypirc with world-readable permissions before changing them after data has been written, which introduces a race condition that allows local users to obtain a username and password by reading this file.
CVE-2012-0876 6 Canonical, Debian, Libexpat Project and 3 more 11 Ubuntu Linux, Debian Linux, Libexpat and 8 more 2025-04-11 4.3 MEDIUM N/A
The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value.
CVE-2013-2099 2 Canonical, Python 2 Ubuntu Linux, Python 2025-04-11 4.3 MEDIUM N/A
Algorithmic complexity vulnerability in the ssl.match_hostname function in Python 3.2.x, 3.3.x, and earlier, and unspecified versions of python-backports-ssl_match_hostname as used for older Python versions, allows remote attackers to cause a denial of service (CPU consumption) via multiple wildcard characters in the common name in a certificate.
CVE-2010-1450 1 Python 1 Python 2025-04-11 7.5 HIGH N/A
Multiple buffer overflows in the RLE decoder in the rgbimg module in Python 2.5 allow remote attackers to have an unspecified impact via an image file containing crafted data that triggers improper processing within the (1) longimagedata or (2) expandrow function.
CVE-2011-4940 1 Python 1 Python 2025-04-11 2.6 LOW N/A
The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 via UTF-7 encoding.
CVE-2010-1634 5 Canonical, Fedoraproject, Opensuse and 2 more 5 Ubuntu Linux, Fedora, Opensuse and 2 more 2025-04-11 5.0 MEDIUM N/A
Multiple integer overflows in audioop.c in the audioop module in Python 2.6, 2.7, 3.1, and 3.2 allow context-dependent attackers to cause a denial of service (application crash) via a large fragment, as demonstrated by a call to audioop.lin2lin with a long string in the first argument, leading to a buffer overflow. NOTE: this vulnerability exists because of an incorrect fix for CVE-2008-3143.5.
CVE-2010-1449 1 Python 1 Python 2025-04-11 7.5 HIGH N/A
Integer overflow in rgbimgmodule.c in the rgbimg module in Python 2.5 allows remote attackers to have an unspecified impact via a large image that triggers a buffer overflow. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-3143.12.
CVE-2010-3492 1 Python 1 Python 2025-04-11 5.0 MEDIUM N/A
The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections.
CVE-2012-2135 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2025-04-11 6.4 MEDIUM N/A
The utf-16 decoder in Python 3.1 through 3.3 does not update the aligned_end variable after calling the unicode_decode_call_errorhandler function, which allows remote attackers to obtain sensitive information (process memory) or cause a denial of service (memory corruption and crash) via unspecified vectors.
CVE-2010-3493 1 Python 1 Python 2025-04-11 4.3 MEDIUM N/A
Multiple race conditions in smtpd.py in the smtpd module in Python 2.6, 2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername function having an ENOTCONN error, a related issue to CVE-2010-3492.
CVE-2013-0340 3 Apple, Libexpat Project, Python 7 Ipados, Iphone Os, Macos and 4 more 2025-04-11 6.8 MEDIUM N/A
expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.
CVE-2012-0845 1 Python 1 Python 2025-04-11 5.0 MEDIUM N/A
SimpleXMLRPCServer.py in SimpleXMLRPCServer in Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an XML-RPC POST request that contains a smaller amount of data than specified by the Content-Length header.
